I don't remember the episode number, but it was the one where the Ropponmatsus get delivered to Excel and Hyatt's apartment. They get trapped in a building with tanks firing at them. Ropponmatsu 2 looks at Excel hungrily then it shows Excel's shadow getting its clothes ripped off. A bunch of images are shown instead of the rape, like a flower losing its petals. Excel mentions that she feels like she lost something.
